This new blood test has demonstrated promise in diagnosing people with Alzheimer\u2019s disease<\/a>. This blood test can allow doctors to detect the disease in persons at genetic risk as early as 20 years before the onset of cognitive impairment.<\/p>\n According to a large international study published in Journal of the American Medical Association<\/em><\/a> (JAMA) and simultaneously presented at the Alzheimer\u2019s Association International Conference.<\/p>\n Alzheimer\u2019s is traditionally diagnosed by characterising amyloid plaques and tau tangles in the brain. An inexpensive and widely available blood test for the presence of plaques and tangles would have a profound impact on Alzheimer\u2019s research and care.<\/p>\n According to the new study, measurements of phospho-tau217 (p-tau217), one of the tau proteins found in tangles, could provide a relatively sensitive and accurate indicator of both plaques and tangles in living people.<\/p>\n \u201cThe p-tau217 blood test has great promise in the diagnosis, early detection, and study of Alzheimer\u2019s. While more work is needed to optimise the assay and test it in other people before it becomes available in the clinic, the blood test might become especially useful to improve the recognition, diagnosis, and care of people in the primary care setting,\u201d said Oskar Hansson, MD, PhD, Professor of Clinical Memory Research at Lund University<\/a>, Sweden, who leads the Swedish BioFINDER Study and senior author on the study who spearheaded the international collaborative effort.<\/p>\nPromising results from the BioFINDER Study<\/h3>\n
